Drag and drop an image PDF to add text to it.

This service will detect whether a PDF has selectable text and will OCR (Optical Character Recognition) that PDF if not. It will allow you to force-override any pre-existing OCR text if detected. Learn more about OCR here.

This is an experimental public service developed to understand the range of PDFs that users need to OCR, and the quality of results that can be delivered across those diverse examples. Your feedback (on twitter: @dwhly) is essential to its optimum development. The service makes use of a leading open source project called OCRmyPDF, which in turn uses Tesseract. In combination these provide the best quality OCR we are aware of, free or paid. This service is provided for free in the same spirit that the open source maintainers have provided their code for free. The code behind this service is available here: [INSERT LINK]
